REVIEW OF THE PI.JeUROIVEC'IdDiE OF SAN FRAIVCI8CO. 



By ^V, N. I.OCKINGTOIV. 



The Phuronectidie of the Pacific Coast have been described by Girard 

 (Proc. Acad. Xat. Sci. Phil. YII, 1854 ; VIII, 185G ; and Pac. Eail. Eep. 

 Vol. X, 145-15G), by Ayres (Proc. Cal. Acad. Sci. 1855, Vol. I, 40, and 

 Vol. II, 1859, 29-30), by Giinther (Cat. Fish. r>rii. I\[ns. Vol. JY^ 1862, 

 pp. 399-457), and by Gill (Proc. Ac. Nat. Sci. Phil. 18G2, 280-281 ; 1864, 

 194-199 ; and 1865, 177). The greater number of the species was charac- 

 terized by the first of these authors ; but as the materials at hand were, 

 insufficient for thorough description, consisting usually of single or im- 

 mature examples, the descriptions were necessarily incomplete. Dr. W. 

 O. Ayres, among the many valuable additions to our ichthyological 

 knowledge made by him during his residence on this coast, added two 

 valid species to the list of our flounders. Dr. A. Giinther enumerates 

 the .'=iX)ecies described by Girard and Ayres, but collocates some of them
